At present, most of the seamless steel tubes produced are hot-rolled. Due to high temperature, the deformation resistance is relatively small. Usually, steel plates are used to complete the rectification and rolling process. In this operation, it is also necessary to consider the specific thickness. If the accuracy requirement is relatively low, there will be no shape problem. The main problem is control. That is, in terms of temperature control, it is also a problem that needs to be considered at the same time. It can be said that this part of consideration is also very important.
There are clear quality requirements for seamless steel pipes in the market, especially for seamless steel pipes with different alloy elements. It is necessary to strictly control harmful elements, and also consider the hazards of pipeline materials after production. Defects such as crack, internal crease, external crease, rolling, delamination, scar, dent and so on also need to be controlled within the specified range to avoid quality problems.
